The on-loan Blackburn man converted Richard Keogh's cross from close range seven minutes from time before United survived a late barrage to hold on for a point.
Anthony Pilkington and Gary Roberts went closest for Huddersfield in a spell of almost constant pressure late on.
Pilkington had earlier rose the highest among a crowd of players to head home his fifth of the season from Roberts' 50th-minutes cross.
But apart from that, the Terriers rarely troubled the visitors until the final 10 minutes.
United's Danny Livesey hit the crossbar early on while Matty Robson also saw a goal ruled out for offside among a handful of good chances for the visitors.
